FLUID-VENDING MACHINE.

Specification of Letters Patent.

Patented Sept. 19, 1916.

Application filed December 28, 1915. Serial No. 69,032.

To all w/mm it may concern Be it known that I, Jason M. CHANDLER, a citizen of the United States, and a resident of Mexia. in the county of Limestone and State of Texas, have invented a new and improved Fluid Vending Machine, which the following is a full, clear, and exact description.

My invention has for its object to provide a fluid vending machine which may be used for vending gasolene and other liquids, the machine being so constructed that it may be regulated to dispense more or less gasolene as desired upon the insertion 'in a coin slot of a coin of a predetermined denomination.

Tn this way, the quantity of gasolene dispensed on the operation of the machine may he changed to agree .with the current price of gasolene.

Another object of the invention is to provide a plurality of coin slots for coins of various denominations, and apparatus for,

dispensing gasolene in large or small quantities, depending upon the particular coin which is inserted before the machine is operated. The regulating means, to change the quantity of gasolene delivered, with the change in the price of gasolene, are so constructed that when operated, they will change the quantity delivered when the machine is operated on the insertion of a coin in any of the said coin slots, the quantity delivered being regulated by the said means with reference to the price of gasolene and the coin slot in which the coin is inserted before the machine is operated.

Another object of the invention is to provide coin-actuated means for moving the parts of the machine into operative position.

Additional objects of the invention will appear in the following specification, in which the preferred form of my invention is describe Reference is had to the accompanying drawings, in which similar reference char acters denote similar parts in all the views, in which v Figure 1 is a front elevation of my invention; Fig. 2 is a side elevation of Fig. 1; Fig. 3 is a sectional view on the line 33 of Fig. 2; Fig. 1 is a sectional view on the line 14 of Fig. 1; Fig. 5 is a sectional view on the line 5-5 of Fig. 3; Fig. 6 is a sectional view on the line 66 of Fig; 3; Figs. 7, S and 9 are enlarged fragmentary views showing the coin-actuating means in different positions; and Fig. 10 is a fragmentary perspective view showing the position of the trigger.

By referring to the drawings, it will be seen that a casing 11 is provided having a base 12, a frame 13 being supported on the base 12 in the casing 11, and having an opening 14 at its top, in which a dispensing member or rod 15 is disposed. This dispensing member or rod 15 extends through an opening 16 in the base 12, so that it may be connected with a pump rod for operating a pump, to dispense the gasolene or other fluid which is to be sold.

Secured to the dispensing member or rod 15 there is a plate 17 having aplurality of vertical guideways 18 in which rack bars 19, 19, 19, 19 and 19 are disposed, the rack bar 19 being provided for dispensing a dollars worth of gasolene when a dollar is inserted in the slot 20 shown in Fig. 1 of the. drawings; the rack bar 19 being provided for dispensing fifty cents worth of gasolene when a fifty-cent piece is inserted in the slot 20; the rack bar 19 being provided for dispensing twenty-five cents worth of gasolene when a twenty-five-cent piece is inserted in the slot 20"; the rack bar 19 being provided for dispensing ten cents worth of gasolene when a ten-cent piece is inserted in the slot 20, and the rack bar 19 being provided for dispensing five cents worth of gasolene when a five-cent-piece is inserted in the slot 20. The teeth of the racks 19, 19, 19", 19, (1 19 are connected by gearing 21, 22, 23 and 24, so that when the rack bar 19 is raised or lowered as may be desired, with reference to the quantity of gasolene which is to be sold for one dollar, the rack bars 19 19", 19 and 19 will be raised or lowered, the gearing being such that when the rack bar 19 is raised one-quarter of the distance between its pin 28 and a horizontal bar 29, the rack bars 19, 19", 19 and 19, will be raised one-quarter of the distances between their pins 28 and the said horizontal bar 29, so that with any increase in the price of gasolene, the amount to be dispensed for fifty cents, twenty-five cents, ten cents, or five cents, will be regulated by the regulation of the rack bar 19 to determine the amount of gasolene to be dispensed for one dollar.

As a means for regulating themovement of the. rack bar 19 relatively to the plate 17,

I provide a transverse shaft '25 which is geared to the teeth of the rack bar 19 for raising or lowering the rack bar, it being possible to rotate the shaft as may be desired by means of the hand wheel 26; the distance it is necessary to move the rack bar 19 by means of the hand wheel 26 and the shaft 25 being indicated by a dial 27. It will therefore be seen that when the dispensing member or rod 15 is raised with the operation of the machine, it will carry up with it the plate 17, which will carry the rack bars, 19, 19, 19 19 and 19, having the pins 28, the said pins 28 being provided for tripping triggers which will shortly be described, for throwing the operating mechanism into inoperative position.

Vhen a twenty-five cent piece is inserted in the coin slot 20*, it will travel along a chute 290 to a shoulder 30 on a rack bar 31, the twenty-five-cent piece being held against this shoulder by an arm 32 mounted on a disk 33 having gearteeth 34 at one side. This disk 33 is secured for moving with a lever 35, and when the twenty-five-cent piece is held against the shoulder 30 in the rack bar 31 by the said arm 32, and the lever 35 is pressed down, the arm 32 in connection with the twenty-five-cent piece will raise the rack bar 31 far enough for its teeth 36 to be positioned where they will be engaged by the teeth 34 at the side of the disk 33, and with the further rotation of the disk 33 by means of the lever 35, the teeth 34 and 36 will serve to raise the rack bar 31, which travels in a guide 37, the rack bar 31 at its upper end 35 engaging an arm 39 secured to a shaft 55, from which another arm 41 extends, the arm being divided and being disposed in an annular groove 42 on a clutch member 43 keyed to a shaft 44, in a manner well understood. This clutch member 43 is provided for engaging a companion clutch members 45 mounted for r0- tating with a pinion 46 which is in mesh with rack teeth 47 on the dispensing member or rod 15. It will, therefore, be understood that When the rack bar 31 is raised by the means which have been described, it will move the clutch member 43 into engagement with the clutch member 45 against the resiliency of the spring 48, so that the clutch member 45 and its pinion 46 may be rotated by means of a crank 49 and the shaft 44, and that with this rotation of the pinion 46, the dispensing member or rod 15 will be raised to operate the pump.

As has been stated, the rack bars 19, 19

19 19, and 19, are provided to limit the movement of the dispensing member or rod 15, so that the amount of gasolene or other fluid dispensed at one time may be regulated with reference to the current price of gasolene and the denomination of the coin inserted in one of the coin slots. This is accomplished in the following manner: Eachof the rack bars 31 has a rearwardly extending wrist pin 50. to which is articulated :1 depending trigger 51. each of the triggers 51 being adapted to be disposed in guideways in the horizontal bar 29. Each trigger 51 moves upwardly with its rack bar 31, so that the trigger .31 may be pressed laterally by its spring 53 to a position where it will rest at its cut-in portion 54 on the horizontal bar 29. the rack bar 31 in its upward position after the disk 33 has beeen rotated to a point where its teeth 34 will leave the teeth 36 on the rack bar 31, and the rack bar'31 will be held upward as has been described until the trigger 51 is moved against its spring 53 so that it may again move back to neutral position in its guideway 52 in the horizontal bar 29. The rack bars 19, 19, 19'". 19 and 19 are moved upwardly with the plate 17 which is secured to the dispensing member or rod 15, which have been described, and the position of the said rack bars 19, 19, 19*, 19 and 19 is adjusted relatively to the plate 17, as has been described, so that they will trip the triggers 51 at predetermined times, to permit the triggers 51 to fall in their guideways 52, thereby permitting the rack bars 31 to move downward. and, by the means which have been described, freeing the clutch member 43 from the clutch member 45, to disconnect the operating mechanism, so that further movement of the dispensing member or rod 15 is. prevented, should theoperator continue to rotate the crank 49.

If a fifty-cent-piece is deposited in the coin slot 20 it will fall against the shoutder 30 on the rack bar 31, and be engaged by the arm on the disk 33. iVhen the lever is pressed down, this will raise the arm 39, which is secured to thishaft thereby serving to move the arm 41 to throw the clutch member 43. in th manner which has been described. The operating mechanism is thrown into operative position by this means, and the operating mechanism is thrown out of operative position after fifty cents worth of gasolene has been dispensed, by means of the pin 28 on the rack bar 19 which will, by the means which have been described, move the trigger 51 against the resiliency of its spring 53-, so that the trigger 51 will move down in its guideway 52 in the horizontal bar 29. The position of the pin 28 on the rack bar 19 is such that it will trip its trigger 51 when the plate 17 has moved upwardly a distance which is one-half of the distance which the rack bar 19 with the plate 17 will move upwardly before the pin 28 on the rack bar 19 trips its trigger .51. Therefore, only one-half as much gasolene will be dispensed when a fifty-cent-piece is deposited in the coin slot 2 a as would be the case where a silver dollar This will serve to hold is deposited in the coin slot 20, and the machine operated. In the same way the plate 17 will move upwardly with the dispensing member or rod 15 one-half the distance that the rack bar 19 will move upwardly With the plate 17 and dispensing member or rod 15, before the pin 28 on the rack bar 19? trips its trigger 51. The arrangement is the same with reference to the pins 28 on the rack bars 19 and 19, th pins on each of the rack bars engaging an inclined surface 50 on a projecting member 57, on its trigger 51.

In Fig. 7 of the drawings, I show the position of the disk 33 with its gear teeth 34. with reference to the rack bar 31 and its teeth 36, before a coin has been introduced in a coin slot. In Fig. 8, I show the relative position of the disk 33 and the rack bar 31 when a coin has been introduced in the coin, slot and the lever 35 has been pressed dmvnward to raise the rack bar 31 to a. position where the gear teeth 31 on the disk are in mesh with the teeth 36 on the rack bar 31. In Fig. 9 of the drawings, I show the relative position of the disk 33 and the rack bar 31 after the disk 33 has been rotated, carrying with it the arm 3:2 to a position where the coin is freed from the arm 32 and the shoulder 30 of the rack bar 31. The disks 30, 30, 30 30, and 30 are ings 59 in which the shaft 58 is journaled.

The shaft 1% is journaled in the bearing 60 in the casing 11, and also in the bearing 61, mounted on the frame 13, the clutch member 1:") being free to rotate on the shaft 41, and the clutch member 43 being keyed to the said shaft 11, in a manner well understood.

Springs (32 are secured to the coin chutes 290 and press against the arms 32 at one side, and springs 63 are secured to the disk 33 and press against the arms 32 attheir other side, for holding the arms 32 yieldingly in position.
